1. A height-limiting rod parameter big data real-time measurement system, the system comprising:

  • the full-color camera equipment is arranged at the position of the roof of the vehicle and is used for executing real-time camera shooting action facing the front of the vehicle body so as to obtain a real-time imaging image;

    the shake detection equipment is arranged on the whole-course camera shooting equipment and used for detecting the shake amplitude and the shake direction of the whole-course camera shooting equipment;

    the shake correction equipment is respectively connected with the shake detection equipment and the full-color camera equipment and is used for adjusting the pixel values of the pixels of the real-time imaging image based on the shake amplitude and the shake direction so as to obtain a content adjustment image;

    the full-color camera equipment also comprises a plurality of imaging units, a flicker detection unit and a drive control unit, wherein the drive control unit is respectively connected with the plurality of imaging units and is used for respectively controlling the imaging parameters of each imaging unit;

    the flicker detection unit is used for detecting whether each of the plurality of imaging units is in the imaging area of the flicker object, taking the imaging unit in the imaging area of the flicker object as the flicker imaging unit, and taking the imaging unit not in the imaging area of the flicker object as the non-flicker imaging unit;

    the drive control unit is connected with the flicker detection unit and used for increasing the exposure of the flicker imaging unit and keeping the exposure of the non-flicker imaging unit unchanged;

    the cooperative measurement equipment is connected with the jitter correction equipment and used for receiving the height-limiting rod object with the shallowest depth of field in the content adjustment image and calculating the actual height of the height-limiting rod object based on the depth of field of the height-limiting rod object and the number of pixels which vertically occupy the most;

    wherein calculating the actual height of the height-limited pole object based on the depth of field of the height-limited pole object and the maximum number of vertically occupied pixels comprises;

    under the condition that the number of the pixels which vertically occupy the most is the same, the deeper the depth of field of the height-limiting rod object is, the higher the calculated actual height of the height-limiting rod object is;

    wherein calculating the actual height of the height-limited pole object based on the depth of field of the height-limited pole object and the maximum number of vertically occupied pixels comprises;

    under the condition that the depth of field of the height-limiting rod object is consistent, the more the number of the pixels which vertically occupy the most is, the higher the calculated actual height of the height-limiting rod object is;

    wherein adjusting the pixel values of the pixels of the real-time imaging image based on the dithering amplitude and the dithering direction comprises;

    adjusting the pixel values of the pixel points of the real-time imaging image in a direction opposite to the shaking direction;

    wherein adjusting the pixel values of the pixels of the real-time imaging image based on the dithering amplitude and the dithering direction comprises; and

    the adjustment amplitude of the pixel value of the pixel point of the real-time imaging image is consistent with the jitter amplitude.
